This application is a division of my cepending application Serial No. 58,540, led Sept.

25, 1925. which has now matured into Patent .ya1,726,360. v

My invention relates generally to radiators, and particularly to radiators ofthe type which maybe advantageously employed 1n automobiles, aeroplanes andin 'general in the -cooling of internal combustion engines and 1.0 the like. f

The invention has among its various objects the production ofdevices of the kind de-v scribed which are durable, eilicient and satis,- factory for use wherever found applicable. A articular obj 'ect-ofthe invention is to provi e' improved radiator construction which will insure that substantially all of the air passing through the radiator will come in contact with the water tubes.

Many other objects andadva-ntag'es of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combinationk of parts herein shown and'described,

and moreparticularly pointed out lin thev claims. In the drawings, wherein-like reference characters "indicate llke or corresponding Parts;

Fig. 1 isga fra entary view in elevation of a radiatorem odying my invention; Fig) 2 is as'ectional view taken on the line 2-'-2 of Fig.1; v

Fig. 3 is a sectional view taken on the line 33 .of Fig.. 2; Y.

- Fig. 4 i' a view similar"v to that of Fig. 2 showing anotherembodiment of my invenv5-5 of Fig. 4.' Referring irst to Figs. 1 11o-3 inclusive, radiators comprising my vinvention embody a plurality of yrelativelyiat or elongated The plates 11 are provided with a plurality of Y The tubes 10' are preferably soldered tothe kdisposed obliquely and at an angle to each tubes 10 which are mounted -'in plates .,11, the plates being arranged in parallel spaced relation to each other transversely of saidtubes apertures 12 for receiving the tubes. The plates 11 are preferably providedV with annuar flanges 13which 'surround the apertures 12, and are designed to closely fit the tubes 10 when arranged in saidapertures.

plates 11- and in practicin '.myf improved method more fully describe in m cepending application Serial No. 58,542, ed Sept. 25, 1925, the lates 11 are rst coated with any suitable su stance to which solderwill not adhere. This coatingis removedfromthe inside of the flanges b fmeans of a wire brush or the like and the tu es and plates are then heldin their assembled positions by-any 'suitable temporary means (not shown) and are dip d a short distance into a' bath of fused sol er so thatV the solder' will flow along the n l vflanges 13 and thus form asjoint between the adjacent surfaces of the tubes and said anges. The solderlows along the flanges but does not adhere tothe coated'surfaces 'of the plates, nor those portions ofthe tubes `disposed between vthe plates. i

.The plates 11 are yprc'ivided vltladpl'urality of rectangular angularly disposed delectors 14 which are produced by lbeing stamped or -fstruck from the platesin suoli a manner as to produce'apertu'res 15'in,the plates' providing air passages. The delectors 14 are preferably .other'as sh'ownin Fig'. 2 so that theywilldirect the air and cause the air passingthrough the radiator to impinge, first one tube -and then the otherof adjacent pairs of tubes. -lt is evident that by providing the plates 11 with apertures and arranging'thedeilectors adjacent the apertures and disposing theA dee ilectors so that they will direct the air toward said tubes that turbulence of the'air betweenl said plates and tubes is created which aug' 0f cev ments the coolin efect of the air upon these tubes. 1 The emodiment of the invention shown in Figs. 4 and 5 substantially correspondsto the-embodiment illustrated in Figs. 1 to 3, except that the deiiectors 14a thereof are bent at an angle to the perpendicular, whereas the defiectors 14 of Figs. 1 to 3 are substantially perpendicular to the plane of the plate 11. From the foregoing description, it is manifest that the structure described provides means whereby air passing through the radiator is 'directed toward the water tubes thereof and that said air is during this passage turbulated, which thereby augments the cooling eiect of the air upon said tubes and furthermore, by the provision of the apertures in the cooling tins or plates of the structure that a portion of the air located between one pair of plates or fins is drawn therefrom to between an adjacent pair of plates, thus'increasing circulation of the air and its cooling effect upon the water contained in the-water tubes of the radiator.

Havingthus described my invention, it is obvious that various immaterial modifications .maybe made in the same without departing from ,the spirit of my invention; hence; I do not wish to be understood. as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.

said tubes and providing means directing air ipto alternate engagement with the front porhon of one tube and thel rear adjacent tube.

2. In a radiator, a plurality of relatively llfjat spaced tubes, ns dlsposed transversely of said tubes, said fins and tubes being secured to each other, members 'formed in said fins for causing turbulence of air passing through the radiator, said members being disposed at 'opposed angles in the space between said tubes and being inclined to the vertical and arranged adjacent the opposite edges of said tubes and providing means directing air into alternate engagement with the front portion of one tube and the rear portionof an adjacent tube.

3. In a radiator, a plurality of relatively flat spaced tubes, fins disposed transversely of said tubes, said fins and tubes bein secured to each other, members projecting rom the plane of the fin for causing turbulence of air passmg through said radiator, said members portionof an
